Hi
when i add LWIP to my project , i get HardFault_Handler on File Lpc17_emac.c on function lpc_low_level_input and in line :

/* Re-queue the pbuf for receive */
lpc_enetif->rx_free_descs++;

stack size is 0x2500

my SCT file is :

LR_IROM1 0x00000000 0x00080000  {    ; load region size_region
  ER_IROM1 0x00000000 0x00080000  {  ; load address = execution address
   *.o (RESET, +First)
   *(InRoot$$Sections)
   .ANY (+RO)
  }
  RW_IRAM1 0x10000000 0x00010000  {  ; RW data
   .ANY (+RW +ZI)
  }
  RW_RAM1 0xA0000000 UNINIT 0x02000000  {  ; RW data
   * (VRAM, GUI_RAM, GUIDEMO_STACK, FS_RAM, IP_RAM, USB_RAM)
    lpc17_emac.o (+RW, +ZI)
mem.o (+RW, +ZI)
memp.o (+RW, +ZI)
  }
}
